Total revenues generated by Abu Dhabi hotels in the first quarter of 2013 rose 15 percent to $389.9m, according to new figures released.
Abu Dhabi Tourism and Culture Authority (TCA Abu Dhabi) also said a total of 631,417 guests checked into accommodation throughout the emirate - a six percent rise on Q1 2012.
Guest nights rose 23 percent to 2,119,016 and the average-length-of-stay was up 16 percent to 3.36 nights at Abu Dhabi's 141 hotels and hotel apartments during Q1.
The Q1 results were aided by a healthy March performance when guest arrivals rose 9 percent which translated into 761,834 guest nights - a 26 percent month-on-month increase with total revenues climbing 18 percent to $136.7m.
The results were also delivered against a background of rising room supply with four new hotel facilities - two resorts, one in Abu Dhabi city another in Al Ain, and two hotel apartments in the UAE capital - opening during Q1 bringing an additional 706 rooms online.
The only negative territory recorded in Q1 was the average room rate which dropped slightly by 2 percent to $133, tourist chiefs said.
"The heightened competitiveness of the destination is winning additional major tour operators to our destination," said HE Mubarak Al Muhairi, director general, TCA Abu Dhabi.
"We are starting to reap the benefits of our trade engagement programme which began a year ago and in which 14 destination management companies have been represented, three of which are now opening offices in Abu Dhabi with a fourth expanding an existing office."
During Q1, domestic tourism continued to be Abu Dhabi's biggest supplier of hotel guests accounting for 202,506 guests, 464,048 guest nights and an average-length-of-stay of 2.29 nights.
On the international front, the UK maintained its position as the emirate's leading overseas guests source market, ahead of India and Germany.
